The Bulldogs (8-1) scored on 12 of 14 possessions and closed the first half on a 27-4 run on the way to a 93-77 victory in front of an announced crowd of 5,356.
"We were all fatigued from the Gonzaga game," sophomore Mike Mercer said. "You could tell we came in lackadaisical and a little sore, and it took us a while to work out way into the game."
The win didn't come without a cost. Junior point guard Sundiata Gaines left after playing just seven minutes in the first half due to a sprained right ankle and did not return. The injury did not require an X-ray, but he is questionable for Friday's 7 p.m. game against Georgia Tech.
"It'll be a game-time decision," said Gaines, who stepped on the foot of a Jacksonville player while pursuing a loose ball. "I'll have treatment every day and do as much as I can to get back."
Mercer auditioned for the point guard spot Tuesday with 11 assists, a career-high and four off the school's single-game record. He also had a career-high eight rebounds and six turnovers to go along with 21 points.
"I've always played point guard growing up, and I think I did a good job coming in today and helping my team win in whatever way possible," he said
Levi Stukes led the Bulldogs with a season-high 27 points, his third straight game of 20 or more, and kept up his torrid 3-point shooting. He hit 7-of-9 from behind the line, including 4-of-4 in the second half, to increase his 3-point shooting percentage to 63 percent this season.
"He's really in the groove right now," Georgia coach Dennis Felton said.
Jacksonville, which fell to 4-7, was led by Lehmon Colbert's 18 points
"I thought we played hard against a very good team who should be ranked in the Top 25," Dolphins coach Cliff Warren said. "We were able to get on them early, but Georgia did a good job of staying poised and they made some shots."
